Data Acquisition is an integral part of machine operation, allowing a machine operator to track, diagnose and monitor systems, processes and components. Analog to Digital Converters (ADC) are vital components to successful data acquisition because they are capable of converting analog signals into digital ones. The AD7789BRMZ-REEL is an ideal application for such conversion.

The AD7789BRMZ-REEL is a single-channel 24-bit delta-sigma Analog-to-Digital Converter that operates over a wide supply range of ±2.7 V to ±3.6 V, with input voltage spans up to ±19.6 V. With a maximum sample rate of 1 Msps and a low power consumption of 500 uW, the AD7789BRMZ-REEL is ideal for applications with power and size constraints such as portable medical and industrial monitoring systems.

The incredible accuracy of the AD7789BRMZ-REEL is provided by its 24-bit resolution and ENOB of 21.5 bits. This accuracy allows systems to detect fine details in the input signal, and to make decisions based on what is detected by the converter. The high resolution of the ADC also increases its accuracy in the face of noise, allowing for messaging systems and communication systems to be built with trustable, precise data.

When interfacing with the AD7789BRMZ-REEL, designers can dedicate to using either SPI or I2C and a reference voltage option. Furthermore, the AD7789BRMZ-REEL supports both voltage mode and thermocouple mode, which can be switched between easily by a single bit in the configuration register. These features create a versatile and simple interface that is ideal for the chosen application.

The AD7789BRMZ-REEL features INT and DRDY outputs, with DRDY being an active-low output that is triggered to ensure data is ready when sampled. A unique feature of this ADC is its power-on reset and empty-input-channel reset functions, which allow both power-on sequencing and the ability to reset the circuitry without additional components.

In terms of its analog specifications, the AD7789BRMZ-REEL features a low input bias current, a maximum gain error of 0.5%, and an ENOB of 21.5 bits, making it perfect for applications with noise and temperature isolation problems. The AD7789BRMZ-REEL also features high common mode rejection ratio (CMRR) of 132 dB, low power consumption of 500 uW, and a wide temperature range of -40°C to +125°C.

The AD7789BRMZ-REEL works in conjunction with operational amplifiers such as the AD822 and the AD8619, allowing users to amplify the input signals to 24-bit resolution. This feature allows noise and signal imperfections to be filtered out, making it ideal for medical and measurement applications. Furthermore, the output of the AD7789BRMZ-REEL can be interfaced directly to microcontrollers or DSPs for further signal processing.

In summary, the AD7789BRMZ-REEL is an ideal Analog-to-Digital converter for medical systems, industrial monitoring systems, communication systems, and other applications with power or size constraints. Its versatility, accuracy, and wide temperature range make it the perfect choice for data acquisition applications.
